Introduction :
Stems are involved to provide support to the leaves and reproduction structures. The vascular tissue that found in stems help in the transportation of water and other substances throughout the plant. The vascular tissues are arranged in group that is surrounded by the parenchyma. The pattern of these vascular tissue arrangement helps to differentiate between eudicots and
Answer to Problem 19A
Correct answer :
The correct answer is option (D).
Explanation of Solution
Explanation/justification for the correct answer :
Option (D) the picture represented in option D is of eudicot and dicot of stem. As we can observe the vascular xylem and phloem of vascular bundles are arranged in a ring shaped around the tissue. So, the correct answer is option (D).
Explanation for incorrect answer :
Option (A) The picture represented in option A is of eudicot and dicot root. We can observe that the xylem is found in the center making X-shape and the phloem are between the arms of X. So, this is an incorrect option.
Option (B) The picture represented in option B is of monocot roots. We can observe the xylem and phloem strands are arranged alternatively surrounded the pith. So, this is an incorrect option.
Option (C) The picture represented in option C is of monocot stem. The xylem and phloem of vascular bundles are grouped together in scattered form. So, this is an incorrect answer.
